but I'm coming to see that actually there's even more to laughter than it's an important social emotion we should look at, because it turns out people are phenomenally nuanced in terms of how we use laughter. There's a really lovely set of studies coming out from Robert Levenson's lab in California, where he's doing a longitudinal study with couples.

In fact, the study never said anything about how long it takes to get over a breakup. It only focused on the aftereffects of ending a relationship, specifically among undergrads, which is a whole other can of worms. To really answer that question of how long it takes to get over a breakup, you would need to do a longitudinal study,

Angela Duckworth
American Psychologist
Childhood is generally far too early to know what we want to be when we grow up. Longitudinal studies following thousands of people across time have shown that most people only begin to gravitate toward certain vocational interests, and away from others, around middle school.

Quote examples
Steve Rushin
American Journalist
When should a man stop wearing sports jerseys? When the buttons of his White Sox top finally pop, like rivets on a distressed ocean liner? When the pinstripes of his Yankees shirt have grown wider at the midsection than at the top, as the longitudinal lines on a globe?

Quote examples
Brad Pitt
Actor
The latitude and longitudinal lines of where you are born determine your opportunity in life, and it's not equal. We may have been created equal, but we're not born equal. It's a lot to do with luck and you have to pass that on.

Australian Scientist
We're collecting about 100,000 telomere lengths in saliva samples and then looking at how those relate to both the extensive longitudinal clinical records that Kaiser is collecting and the genome sequence variations.
